Comparative financial statements are not required; however, SEC requirements specify that most registrants provide two years of comparatives for all statements except for the balance sheet, which requires only one comparative year.
One year of comparatives is required for all numerical information in the financial statements, with limited exceptions for certain disclosures.
A third statement of financial position at the beginning of preceding period is required for first-time adopters of IFRS and in situations where a retrospective application of an accounting policy, retrospective restatement or reclassification having a material effect on the information in the statement of financial position at the beginning of the preceding period have occurred. Restatements or reclassifications in this context are in relation to correction of errors, or changes in presentation of previously issued financial statements.
